Now things are looking a bit more fixie ish.
1) Had to measure frame width to determine which spacers are required on rear axel. In the end 3 washers on each side just allowed the frame to pull in slightly and hold the wheel in place.
2) Chain tensioners also fitted, this will allow chain tensioning - obviously! and prevent the wheel being pulled forward under load
3) The rear hubs are not track hubs with 2 threads on them, one for the sprocket, the other for a locknut with a left hand thread. Instead I am using a conventional hub originally designed to a screw on free wheel. The sprocket will screw straight on which is great, also there is sufficient thread protruding to allow a lock nut, did you know that a locking ring from a Bottom bracket will fit? Ok, I know it is not as good as a track hub with a left hand thread but it will do the job. Therefore the thread was degreased and the lock nut fitted using loctite,
